Description

A kind of no post large span underground space structure
Technical field
The utility model relates to a kind of underground space structure, particularly a kind of large span underground space structure.
Background technology
Receive the restriction of town site, existing mode of transportation can not have been carried so huge volume of the flow of passengers, and the development and utilization of the underground space has become a main trend of urban development.But the building that stands in great numbers in the city, intensive road traffic and all kinds of network of underground that gather in length and breadth; Make the surrounding enviroment in city become increasingly complex; Should rationally open and send out the underground space of utilizing the city; The existing environment of safekeeping periphery again, this just need seek a kind ofly can the underground structure form of the inner space of efficient utilization can be provided again for underground space construction provides the safety support form.
Large span underground space structure commonly used now generally includes space enclosing structure and internal construction, and said space enclosing structure is generally liner structure or section of jurisdiction supporting.Because liner structure or section of jurisdiction supporting and protection structure produce disturbance to surrounding soil easily at work progress; Cause space enclosing structure can not guarantee the construction safety of internal construction fully; Thereby before the internal construction construction, it is that safe construction provides supporting that the collaborative space enclosing structure of edge column or side wall need be set in advance.For the bigger underground space structure of span, just there is a large amount of support of work progress needs in above-mentioned space enclosing structure form commonly used, because the existence of edge column, the internal construction space function such as is restricted at defective on dividing.
The utility model content
The purpose of the utility model provides a kind of no post large span underground space structure; The space enclosing structure that solves traditional large span underground space structure can not be guaranteed the technical problem of the construction safety of internal construction fully, and solves edge column supporting meeting in traditional large span underground space internal construction and cause the underground structure built-in function to divide limited technical problem.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of no post large span underground space structure; Comprise space enclosing structure and internal construction; It is characterized in that: said space enclosing structure is surrounded by the jacking steel pipe of connection arranged side by side and forms, and the vertical jacking of said jacking steel pipe is planned to build in the soil body of underground space structure bearing of trend, and said jacking steel pipe gathers according to the outline of planning to build underground space structure; In the pipe of jacking steel pipe interstitital texture is arranged; The side direction adjacent of jacking steel pipe is connected with otch supporting and protection structure side by side, and said otch supporting and protection structure is communicated with the jacking steel pipe sidewall of both sides, and the soil body between the said jacking steel pipe forms the grouting and reinforcing soil body through slip casting.
The said outline of planning to build the underground space is rectangle or arch.
The every joint length of said jacking steel pipe is 4~6m, has injected hole on its tube wall at interval.
Said space enclosing structure bottom forms the bottom side wall enlarged footing through a large amount of slip castings. ? 
Said otch supporting and protection structure comprises supporting between fixation steel plate, waterproof steel plate and pipe, and said waterproof steel plate is arranged on the outside of internal construction; Said fixation steel plate is arranged on the inboard of internal construction; Supporting is propped up and is withstood between fixation steel plate and the waterproof steel plate between said pipe.
Said internal construction comprises plate and structure base plate in the structure; Be provided with or be not provided with the structure center pillar in the said structure between plate and the structure base plate.
Said structure base plate bottom surface is provided with base plate waterproofing, and its upper surface is provided with base plate fill concrete layer.
Compared with prior art the utlity model has following characteristics and beneficial effect:
At first; The utility model forms the pipe curtain through the large diameter steel pipe jacking of adopting; To manage the perforation of curtain steel pipe transverse links into an integrated entity; The construction that can be the large span underground space structure provides safe outer peripheral protection structure, and whole construction is basically all operated in steel pipe, piping lane, reduces the underground space construction security risk greatly.Whole construction course need not take road, need not pipeline and changes and move, and environmental-protecting performance is strong.
Secondly, connection place guarantees that through at the face down bonding steel plate for sealing water that meets water all there is the steel outsourcing in the whole underground space structure outside between the steel pipe pipe, add self concrete structure from waterproof, waterproof effect is good, guarantees that waterproof is perfectly safe.But have water stratum submersible need not through dewatering guarantee the construction normally carry out.
Moreover the said underground space structure form of the utility model is less to the ground settlement influence at work progress, can realize zero sedimentation; During construction periphery being built (structure) thing influences very little; Need not it is carried out processing such as ground stabilization, can effectively accelerate the construction period, practice thrift construction cost.
In addition; The said underground space structure form of the utility model main auxiliary part in work progress can adopt steel mostly; Construction all recyclable the recycling that finish meets environmental protection and energy saving theory in the modern project construction, thereby reduces the construction cost of series engineering significantly.
The utility model can be widely used in being widely used in underground engineering construction, and it is numerous to be particularly useful for surrounding building, and underground utilities enrich the underground construction of section.
